Yes! This is the key to migrating a list to a new version in any
context. See the definition of CheckVersion() in Mailman/MailList.py.

Whenever a list is loaded from config.pck (or even a 2.0.x config.db),
the data version from the file is compared to the version of the
installation, and if it is less, Update is imported from
Mailman/versions.py and called to migrate the list data to the current
version. This is why you can drop a config.pck from an older version
into a running newer version and it just works.
